323 | If C<$enable> is true (or missing), then the C<encode> method will not |
|
|
324 | barf when it encounters a blessed reference. Instead, the value of the |
|
|
325 | B<convert_blessed> option will decide wether C<null> (C<convert_blessed> |
|
|
326 | disabled or no C<to_json> method found) or a representation of the |
|
|
327 | object (C<convert_blessed> enabled and C<to_json> method found) is being |
|
|
328 | encoded. Has no effect on C<decode>. |
|
|
329 | |
|
|
330 | If C<$enable> is false (the default), then C<encode> will throw an |
|
|
331 | exception when it encounters a blessed object. |

|
|
334 | |
|
|
335 | If C<$enable> is true (or missing), then C<encode>, upon encountering a |
|
|
336 | blessed object, will check for the availability of the C<TO_JSON> method |
|
|
337 | on the object's class. If found, it will be called in scalar context |
|
|
338 | and the resulting scalar will be encoded instead of the object. If no |
|
|
339 | C<TO_JSON> method is found, the value of C<allow_blessed> will decide what |
|
|
340 | to do. |
|
|
341 | |
|
|
342 | The C<TO_JSON> method may safely call die if it wants. If C<TO_JSON> |
|
|
343 | returns other blessed objects, those will be handled in the same |
|
|
344 | way. C<TO_JSON> must take care of not causing an endless recursion cycle |
|
|
345 | (== crash) in this case. The name of C<TO_JSON> was chosen because other |
|
|
346 | methods called by the Perl core (== not the user of the object) are |
|
|
347 | usually in upper case letters and to avoid collisions with the C<to_json> |
|
|
348 | function. |
|
|
349 | |
|
|
350 | This setting does not yet influence C<decode> in any way, but in the |
|
|
351 | future, global hooks might get installed that influence C<decode> and are |
|
|
352 | enabled by this setting. |
|
|
353 | |
|
|
354 | If C<$enable> is false, then the C<allow_blessed> setting will decide what |
|
|
355 | to do when a blessed object is found. |
